The best Fusion 360 replacement depends on what you need to leave behind. Reddit users cite changing license rules, the cloud workflow and crashes, but their experiences vary: one commenter says the personal license still works for them. FreeCAD is the closest free, open-source option in this list. Onshape suits teams comfortable with cloud CAD; SOLIDWORKS, SketchUp and AutoCAD fit different design workflows. Blender is for broader 3D work, not a like-for-like CAD swap.
01Why people leave Fusion 360
License rules and limits
Reddit users complain about changing licensing. One commenter says personal use still works, with a limit of 10 editable documents at once.
Cloud-dependent workflow
One Reddit thread specifically asks for a free, non-cloud alternative. A commenter says they wish Fusion offered a fully local option.
Crashes and slow calculations
Some Reddit users report freezes, crashes and slow calculations, including after updates. These are individual reports, not proof every user has the same problems.
02The alternatives, ranked by fit
- Best free CAD
FreeCADFreeCADFreeCAD is the clearest fit if the bill, licensing changes or cloud workflow are why you’re leaving. A Reddit commenter describes it as free and open source, with no licenses or upgrade pressure, and says it runs on Linux, Windows and Mac. The alternatives listing includes a free plan; the same commenter warns it is less polished and can be glitchy.
Trade-off: Expect a learning curve and quirks; it is not as polished as Fusion 360, according to a Reddit user.
7.0/10from
Freefree plan - Best for shared CAD
OnshapeOnshapeOnshape may suit you if you want a different CAD workflow for a team rather than a local, non-cloud tool. The listing highlights shared CAD workflows and integrated PDM for commercial users. One Reddit user says it felt familiar after Fusion, but could not confirm it had all of Fusion’s features. Its listed starting price is $125, with a free plan.
Trade-off: It is cloud CAD, so it does not answer a request for a non-cloud workflow.
6.8/10from
$125/mofree plan - Best for parts
SOLIDWORKSSOLIDWORKSConsider SOLIDWORKS for professional parts and assembly design rather than assuming every Fusion workflow will transfer directly. Its listing names professional parts and assembly design as a fit, with a starting price of $2 and a free plan. A Reddit commenter describes SOLIDWORKS for Makers at $50 per year, launched through a browser but running locally.
Trade-off: Check license terms; Reddit’s Maker option still launches through a browser.
6.8/10from
$2/mo - Best for 3D design
SketchUpSketchUpSketchUp is worth considering if your work is design-led and you need both 3D and 2D documentation, rather than a direct CAD/CAM replacement. Its listing also names model review and extensions as strengths. The listed starting price is $2.5, with a free plan; the listing cautions that the desktop workflow comes with a meaningful annual bill.
Trade-off: It is not presented as an all-in-one CAD-to-manufacturing replacement.
6.8/10from
$2.50/mofree plan - Best for DWG drafting
AutoCADAutoCADAutoCAD fits teams whose main requirement is precise 2D technical drafting or a DWG-based workflow. Its listing also points to specialized CAD toolsets. The starting price is listed as $175, with a free plan. That makes it a narrower alternative to consider when drafting matters more than Fusion 360’s combined design and manufacturing scope.
Trade-off: The listing flags price and workflow fit as reasons to skip it.
6.5/10from
$175/mofree plan - Best for broad 3D
BlenderBlenderBlender makes sense if your priority is broad 3D work and avoiding subscription costs, not replacing parametric CAD or manufacturing tools feature for feature. The listing describes it as free and notes varied workflows and Python customization. It is a different kind of tool, so compare the work you actually need to do before moving a CAD project into it.
Trade-off: It is not positioned as a like-for-like CAD/CAM replacement; add-ons may cost extra.

Questions people ask
What is the closest free alternative to Fusion 360?
FreeCAD is the closest match in this list for someone seeking free CAD without subscription pressure. A Reddit commenter describes it as open source and available on Linux, Windows and Mac, but also says it is less polished and can be glitchy. The listing marks it as having a free plan.
Which Fusion 360 alternative is not cloud-based?
FreeCAD is the strongest fit among these picks if avoiding cloud CAD is the priority: a Reddit commenter says it runs on Linux, Windows and Mac. A separate commenter describes SOLIDWORKS for Makers as launching through a browser while running locally. The sources do not establish that every SOLIDWORKS plan works that way.
Is Onshape a good replacement for Fusion 360?
Onshape may work for teams that want shared CAD workflows and integrated PDM and accept cloud CAD. One Reddit user says the interface felt familiar after Fusion 360, but could not guarantee feature parity. The listing shows a $125 starting price and a free plan, so check whether its workflow and pricing suit your team.
